First, I will admit that the price is outrageous for this simple little piece of plastic (and the included DVD, which you can watch in advance on YouTube), but I tell you what, this thing absolutely does what it claims to do! After just a couple of practice sessions (swinging in the back yard), not only am I swinging on plane, but I am able to detect other swing flaws (like cranking my hips too early which opens the club face). Over a short period of time, I feel like I am naturally "in the groove" when I swing, and I am thinking less about all of the mechanics. This thing definitely helps to create muscle memory and the natural (and correct) feel for the golf swing. On my first golf outing after working 10 minutes for 5 consecutive nights with the Swingyde, I played the best golf I have ever played. My club face was square and I connected with the ball better than I ever have. (I generally shoot in the 110 range and on this last round, I scored 98). If you are handy with tools, you may be able to rig up something like this product, but for the rest of us, spend the $25 and get "on plane". If the rating scale went to 10, I would rate this product a 10.
